That is a fair ask. To be honest, I am unwilling to devote to this discussion the time which would be required to research examples.
I will concede that if these things never happened, I personally would find the infohazard argument non-compelling, though others may have their own feared infohazards.
On the flip side, if hypothetically these were common ideas animating public school curricula and/or teacher behavior, would you consider that sufficient justification for homeschooling as being discussed here?
When it comes to public policy, I don't find myself particularly animated by hypotheticals. I think we have more than enough on our plate if we just pay attention to things that are actually happening in the large.
